To all whom z't may' concern: t. v

Be it known that YUICIII OI;AMT0, a subject ofthe Emperor'off'dapan,residing at Tokyo, Japan, has invented certain new and usefulImprovements in Perforators, of which the following is a s eciication.

The present invention re ates to improvements in keyboard perforators.

More particularly, the-'invention relates to-a perforator fortelegraphic and like purposes in which code combinations are perforatedin tape which is then used -to control A perforator of this character isdisclosed in U. S. Patent .No 1,085,985 issued to Edward E;'Kleinschmidt," February 13, 1914, yand the preferred embodimenthereinafter disclosed will be set forth as a plied to the perforatordisclosed in the sai patent, so much' only of the old structure beingshown as will be necessary for an understanding of the presentimprovement to be had.

An obect of the invention is to increase the num er of-combinationswhich may be first descri perforated on the mechanism withoutY in-rcreasing the number of keys on the keyboard.

Other objects of the invention are such as will appear in the yfollowingdetailed disclosure of the preferred embodiment of The drawing is a fraental side elevation, more` or less in iagram and with parts omitted toclearly set forth improvement and its relation to the old structure'.

Referring to the drawin thesame reference characters are lused orsimilar parts' as has been applied thereto in the above mentioned patentand the old parts will be ed. 1 represents the key bars which arefulcrumed about bar 2, it being understood that a bank of keysl areused. Arranged longitudinallyv of and beneath,

i each key bar'is a notched bar 3v fulcrumed on transverse bar 4,- andretained in normal upward position by a spring 5 individual toeachmtched bar 3, secured upon each key bar 1 are guide plates -6between whichbars 3 rest to prevent sidewise movement thereof. Each'bar3 has a/short projecting section of its upper edge to pass between theguide plates as shown. A transversely extendin stop 7 limits thedownward movement of ars 3 'when depressed by `the key l bar, and a stop7 limits the upward movement of the key bars. J or selector bars 8' arearranged in the manner shown in Patent No.v 1,085,985 and control thepunch-selectors and mechanisms in the manner set forth in said patent,so that depression of any bar' 8 causes a corresponding punch to be oerated.

. e apparatus so far described is'oldand f mannerfto shift bars 3 bodilywith relation to bars 8 and key bars 1. Secured to eX-` stension 10 ofthe fulcrum block is al spring 11 which holds the fulcrum 4 togetherwith bars 3 in rearward position or to the right in the drawing."Rigidly secured to the fulcrum block is a shift key bar 12 which whendepresse/d will throw the fulcrum 4 to ether with bars 3 forward. In therearwar position of key bars 3 a oup of projections 13 thereof will bedirect y over bars 8 and pro-- jections 14 will be between bars 8 sothat cwhen the Jkeys are depressed pro'ections 13 only will setcombinations of punc es. With shift-bar 12 raised, only pro]ections 14will set punches when a key is depressed.. It will ofcourse beunderstood that the arrangements and numbers of projections 13 arevaried on each key bar in a manner to setup the various desiredcombinations.

In order to prevent" thefinterference of bars 8 with thfeJ shiftingmovements of the bars 3 stop plates 15 are provided which limit' theupward movement of bars 8 and prevent engagement of teeth 13 vand 14therewith when keys 1 are in normal upper position.-

By. utilizing the described arrangement it will be seen that each keywill perforate`2 or more characters depending on the number of shiftpositions provided. Such perforators are particularly adapted forperforation lof code arrangements. for Japanese and like ,alpabets'where a relatively great num- 'n ber of different characters must beperforated.

Having described a preferred, embodiment of the invention what isdesired to be secured by Letters Patent and claimed as new 1s:

1. A perforator comprising a plurality of punch controlling selectors,la plurality of `members arranged to control such punch selectors invarying combinations, and means for shifting said members with relationto said punch selectors in a` manner to change the combinationscontrolled by said l members.

prises apivoted fulcrum for said members.

4. A tape perforator comprising a plurality of key levers; a pluralityof code combination bars each of which carries two or more codecombinations and is associated With one of said key levers; and meansfor displacing said bars according to the code combination carriedthereby which it isdesired to perforate.

5. The combination as set forth in claim 4 in which said codecombination bars are fulcrumed on a common member to ether with meansfor displacing said mem er.

6. The combination as set forth in claim 4 in which the code combinationbars are pivoted on a pivoted .fulcrum block, together with means forshifting said fulcrum block about its' pivot.
